Measurement of the area and mass of a test piece and calculation of its mass per unit area in grams per square metre. In order to meet the specific needs of nonwovens, alternative requirements to those listed in ISO 3801 are specified in this part of ISO 9073. These are: a) a different sampling procedure; b) an alternative specification for dimensions of test piece; c) a greater accuracy for the balance.
